Canarene (1), a triterpene with an unprecedented carbon backbone, was isolated from Canarium schweinfurthii. It is the first member of a new class of triterpenoids, for which the name 鈥渃anarane鈥欌€?is proposed. 1 showed weak 伪-glucosidase inhibitory activity, and its structure was unambiguously deduced by single-crystal X-ray diffraction.
